Definitions

  • the present invention relates to an overhead traveling vehicle.
  • the present invention relates to a technique of reading IDs of transported articles.
  • US 2006237525 shows an an ID reader provided at a fall prevention cover of an overhead travelling vehicle for reading an ID on the back surface of an article.
  • the ID reader can be protruded from or retracted into the fall prevention cover. When the article is elevated/lowered, the ID reader is retracted into the cover. When the ID is read, the ID reader is advanced to a position under the article.
  • US 4791282 discloses an X-ray film cassette having on its top a triangular bar code field readable by a bar code reader of an automatic film sheet charging and discharging apparatus.
  • the bar code field is in the form of an isosceles right triangle whose hypothenuse faces a reference corner and whose legs extend parallel to edges of the cassettes.
  • the bars of the code extend parallel to the hypothenuse.
  • An optical axis of the bar code reader when the cassette is in its end position in the apparatus, intersects a vertex area formed by the legs of the triangle. This arrangement guarantees that its bar codes on cassettes of small format, even if misaligned in the feeding direction, are reliably read by the reader.
  • An object of the present invention is to make it possible to reliably read IDs of articles. Another object of the present invention is to prevent the increase in the cycle time for transportation due to reading of IDs. Still another object of the present invention is to prevent obstruction of elevation and lateral movement of an article by an ID reader of an overhead traveling vehicle.
  • the invention refers to an overhead traveling vehicle according to claim 1 and to a method according to claim 6.
  • An overhead traveling vehicle comprises an ID reader for reading an ID of an article, and means for moving the article in a lateral direction perpendicular to a traveling direction of the overhead traveling vehicle in a horizontal plane.
  • the article is moved in the lateral direction for allowing the ID of the article to be read by the ID reader.
  • the ID of the article is read by the ID reader while moving the article in a lateral direction perpendicular to a traveling direction of the overhead traveling vehicle in a horizontal plane.
  • the article is moved in the lateral direction during traveling of the overhead traveling vehicle for allowing the ID of the article to be read by the ID reader.
  • the overhead traveling vehicle further comprises an elevation frame for suspending, and elevating the article from a load port for processing equipment to a storage position, and the ID reader is provided at a position deviated from an elevation path of the article, below a bottom surface of the article elevated to the storage position, for reading the ID attached to a lower position of the article.
  • the overhead traveling vehicle further comprises an elevation frame for suspending, and elevating the article from a load port for processing equipment to a storage position, the ID reader is provided at a position deviated from an elevation path of the article, and after the article is elevated to the storage position, the elevation frame and the article are moved in the lateral direction by a predetermined distance, away from the processing equipment for allowing the ID to be read by the ID reader during movement in the lateral direction.
  • the ID reader by moving the article in the lateral direction to read the ID using the ID reader, even if the ID reader failed to read the ID at the first position, the ID can be read during the lateral movement. Thus, reading failures of the ID can be almost eliminated.
  • the overhead traveling vehicle further comprises an elevation frame for suspending, and elevating the article from a load port for processing equipment to a storage position, and the ID reader is provided at a position deviated from an elevation path of the article, below a bottom surface of the article elevated to the storage position, for reading the ID attached to a lower position of the article, elevation and lateral movement of the article are not obstructed by the ID reader.
  • the ID can be read during lateral movement for preventing interference between the processing equipment and the article. If reading of the ID fails, the following processes may be carried out for example.
  • the overhead traveling vehicle may start traveling, and move the article laterally in a segment without any interference between the processing equipment and the article. In this case, start of traveling is not delayed due to the failure of reading the ID. Alternatively, the overhead traveling vehicle may remain stopped, and move the article laterally back and forth to the right and left. After reading of the ID is finished, the article is moved in the lateral direction away from the processing equipment, and traveling is started.
  • the segment without any interference between the processing equipment and the article is a straight segment or a segment without any processing equipment, on a map of travel routes stored by the overhead traveling vehicle.
  • FIGS. 1 to 4 show an overhead traveling vehicle 4 according to an embodiment and its operation.
  • a reference numeral 2 denotes a travel rail
  • reference numerals denote 3 support columns.
  • the travel rail 2 is supported by the support columns 3 from a ceiling of, e.g., a clean room.
  • An overhead traveling vehicle 4 travels along the travel rail 2 by a travel drive unit provided inside the travel rail 2.
  • the overhead traveling vehicle 4 has a power reception unit in the travel rail 2 for receiving electricity in a non-contact manner.
  • the travel drive unit of the overhead traveling vehicle 4 supports a base 6, and a lateral drive 8, a ⁇ drive 10, and an elevation drive unit 12 are provided under the base 6.
  • the lateral drive 8 moves the ⁇ drive 10 and the elevation drive unit 12 in a lateral direction.
  • the ⁇ drive 10 rotates the elevation drive unit 12 in a horizontal plane.
  • the ⁇ drive 10 may not be provided.
  • a direction perpendicular to a traveling direction of the travel rail 2 is referred to as the lateral direction.
  • the elevation drive unit 12 elevates and lowers an elevation frame 14.
  • the elevation frame 14 has a pair of chucks 16 for supporting the bottom surface of a flange 18 of a cassette 20 as a transported article, to elevate or lower the cassette 20.
  • a reference numeral 21 denotes a lid of the cassette 20.
  • An ID 23 is attached to the cassette 20 at the center at a lower position on the back surface side as viewed from the lid 21 of the cassette 20.
  • a barcode or an RFID is used as the ID 23.
  • a pair of safety covers 22 are provided on the front and rear sides of the base 6 of the overhead traveling vehicle 4.
  • Safety claws 24 are provided below the safety covers 22.
  • the safety claws 24 are pulled into or pulled out of the safety covers 22 for preventing the cassette 20 from being dropped undesirably.
  • An ID reader 26 is provided on an arm 25 extending from, e.g., one of the front and rear safety covers 22.
  • the ID 23 of the cassette 20 is read using the ID reader 26.
  • a position where elevation of the elevation frame 14 is finished, and the overhead traveling vehicle 4 stores the cassette 20 is a storage position of the cassette 20.
  • the upper surface of the ID reader 26 is lower than the bottom surface of the cassette 20 at the storage position.
  • the ID reader 26 is provided outside an elevation path of the cassette 20 in the lateral direction.
  • the ID reader 26 does not interfere with elevation or lateral movement of the cassette 20.
  • the arm 25 is rotatable in the horizontal plane. For example, the arm 25 may move back and forth between a position where the ID reader 26 is stored on the safety cover 22 side, and a position where the ID reader 26 is outside the elevation path below the ID 23.
  • cassettes 20 There are various sizes of cassettes 20. Therefore, when the cassette 20 is simply elevated to the storage position, it may not be possible to read the ID 23 by the ID reader 26. In the case where it is not possible to read the ID 23, it is not possible to confirm which cassette is being transported by the overhead traveling vehicle 4. Therefore, it is necessary to reliably read the ID 23 of the cassette 20. Further, it is not preferable that the cycle time of the overhead traveling vehicle increases due to reading of the ID 23.
  • FIG. 3 shows an algorithm of reading an ID.
  • the elevation frame 14 is lowered, and the flange 18 of the cassette 20 is supported by the chucks 16. Then, the elevation frame 14 is elevated by the elevation drive unit 12 to the storage position to finish elevation. Thereafter, the safety claws 25 move forward from the safety covers 22, and the overhead traveling vehicle 4 starts traveling along the travel rail 2. Then, at a suitable timing, e.g., when elevation of the cassette 20 is finished, the ID reader 26 reads the ID 23. Reading of the ID 23 can be started at an arbitrary timing after the cassette 20 is elevated, and the ID 23 passes a position near the ID reader 26. At the time of reading the ID 23 for the first time, if reading of the ID 23 fails, the cassette 20 moves laterally to the left or the right as described later, for attempting to read the ID 23 again.
  • the lateral drive 8 moves the ⁇ drive 10, the elevation drive unit 12, and the elevation frame 14 laterally.
  • the ID reader 26 reads the ID 23.
  • the cycle time of the overhead traveling vehicle 4 does not increase.
  • FIG. 4 schematically shows lateral movement of the cassette.
  • the cassette is moved in a lateral direction from the position where elevation is finished (storage position).
  • the ID is read.
  • the cassette is moved laterally by a predetermined distance toward the ID reader on the side opposite to the lid of the cassette.
  • the ID is read. If the ID is read successfully, after the cassette is pulled toward the ID reader by the predetermined distance, the lateral movement is stopped. In this manner, by transporting the cassette at a position remote from a position right above the load port, i.e., at a position remote from the processing equipment in the lateral direction, interference with the processing equipment is reliably prevented.
  • the cassette 20 is moved back in the lateral direction to attempt to read the ID again. If the ID is read successfully during the lateral movement, the lateral movement of the cassette is stopped, and the cassette is held at a predetermined position. It should be noted that the ID may be read while moving the cassette laterally, or the ID may be read after temporarily stopping the cassette during the lateral movement.
  • the overhead traveling vehicle elevates the cassette 20 using the elevation frame 14.
  • FIG. 5 shows an algorithm of reading an ID according to a modified embodiment.
  • the modified embodiment is the same as the above-described embodiment except the timing of reading the ID.
  • a plurality of pieces of processing equipment (not shown) are provided on one of the left and right sides of the travel rail 2 for the overhead traveling vehicle 4.
  • Load ports for the processing equipment are provided right under the travel rail 2.
  • the arm 26 having the ID reader 26 is fixed at a position deviated from the elevation path of the cassette 20 (article). This position is opposite to the processing equipment in the lateral direction, as viewed from the travel rail 2.
  • the overhead traveling vehicle 4 transfers the article to or from the load port for the processing equipment by elevating, and lowering the elevation frame 14.
  • the overhead traveling vehicle 4 stores a map having data of the travel routes and the layout of the load ports. In the map, the travel routes are divided, e.g., into straight segments, curve segments, and diverging (merge) points.
  • the overhead traveling vehicle 4 starts to read the ID using the ID reader 26.
  • the safety craws 24 move forward to the cassette 20.
  • the overhead traveling vehicle 4 moves the elevation frame 14 and the cassette 20 laterally, to a position opposite to the processing equipment.
  • the lateral direction is a direction perpendicular to the traveling direction in a horizontal plane. All the pieces of processing equipment are provided on one of the left and right sides of the travel rail 2.
  • the elevation frame 14 and the cassette 20 While moving the elevation frame 14 and the cassette 20 away from the processing equipment by a predetermined distance, e.g., by 10 to 100mm, if the ID is read successfully, reading is finished, and the overhead traveling vehicle 4 starts to travel along the travel rail 2. At this time, the cassette is transported at a position moved by the predetermined distance laterally to the left or right, oppositely to the processing equipment.
  • a predetermined distance e.g., by 10 to 100mm
  • the overhead traveling vehicle 4 starts traveling, and moves the cassette to the left or right toward a position near the processing equipment in lateral direction, from the predetermined position.
  • the stroke of the lateral movement is about 10 to 100mm from a position right above the load port, in both of the direction to the left and the direction to the right. Interference between the cassette and the processing equipment may occur when the cassette is swayed in the curve segment or the like, and protrudes from the overhead traveling vehicle 4 toward the processing equipment. Therefore, in the case of the stroke of about 10 to 100mm from a position right above the load port, in both of the direction to the left and the direction to the right, no interference occurs in the absence of any sway.
  • the overhead traveling vehicle 4 identifies whether the overhead traveling vehicle 4 is traveling along the straight segment or the curve segment based on the map or the like, and the lateral movement is carried out in the straight segment where no significant sway occurs. If the ID is read successfully, the cassette is moved laterally to the predetermined position. Alternatively, the overhead traveling vehicle may detect a segment without any load ports based on the map to move the cassette laterally. In the case where ID cannot be read even if the lateral movement is repeated in several cycles, for example, it is determined that a reading error occurs.
